Jaw appliances for overbite and airway in teens
Part of Mouth & dental clinical trials.
This trial compares two dental appliances—Twin Block and Myobrace—to see which one better improves your airway and facial shape during the teenage growth spurt. If you have a set-back lower jaw and moderate overbite, participating could help guide your jaw growth and breathing.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 10 and 14 years old and still growing.
- You have an overbite where the upper jaw is normal but the lower jaw is set back (skeletal class II).
- Your front teeth stick out 6 to 10 mm (about the width of two pencils).
- You have a rounded facial profile (not flat or concave).
- Your teeth are mostly straight with little to no crowding.
- You have never had braces or jaw treatment before.
- You do not have an open bite, facial asymmetry, or cleft lip/palate.

This trial tests a special 3D-printed brace to fix underbite in children aged 8-13 who still have growing upper jaws. The brace encourages the upper jaw to grow forward and corrects the bite.
This study tests a removable orthodontic device (twin-block with clear plates) to improve how the upper and lower jaws fit together in children. It may help if you have a specific “Class II” jaw pattern caused mainly by a lower jaw that sits back.
This study compares two types of braces (functional appliances) used to fix an overbite caused by a lower jaw that is too far back. It looks at which brace works better for growing teenagers. If your child needs jaw alignment, this trial could help them get treatment.
This study compares two types of braces to fix an overbite in teens who have finished most of their facial growth. It also looks at how having a misaligned bite affects daily life and how treatment may improve it.
This trial compares a facemask device with upper braces to correct underbite in children ages 7–10. It aims to find which treatment works better to align the jaw and teeth.
This study compares two different dental braces to see which one works better for improving jaw position and breathing in children whose lower jaw is set back. It may help your child's jaw grow in a healthier way.
